Orthodontics can produce an amazing smile transformation. With today’s advanced appliances and techniques even the most difficult malocclusions (bad bites) can be overcome. All of this innovation, however, depends on one basic anatomical fact: though firmly set in the mouth, our teeth can still move.
Teeth are actually held in place by the periodontal ligament, a strong, elastic tissue that attaches to them through tiny collagen fibers on one side of the ligament and to the jawbone with similar fibers on the other side. When pressure is placed against a tooth, the bone on the opposite side of the force begins to dissolve (resorb), allowing the tooth to move. As it moves, new bone is built up behind the tooth, to stabilize it. Orthodontists take advantage of this natural mechanism through orthodontic hardware like braces that applies pressure in the desired direction of movement, while the ligament and bone do the rest.
There is, though, a downside to this process. The teeth, bone and gum tissues can contain a kind of “memory” for the former natural position of the teeth. Over time, the lower front teeth tend to take a gradual migratory movement back towards their original position. Also, as we age the lower front teeth may crowd each other as there is a genetic influence for teeth to move to the midline of the face, causing a pressure that allows the skinny lower front teeth to slip behind each other. As a result of both of these tendencies, corrected teeth may retreat from their new positions.
To stop these tendencies, we use an appliance known as a retainer after braces or other hardware is removed. As the name implies, this appliance “retains” the teeth in their new position. For structural “memory,” the retainer will keep the teeth in their new position until the impulse to return to the old one has faded, about eighteen months. Retainers can also slow or stop the natural genetic influence of movement, but it may mean wearing a retainer for an indefinite period, especially individuals who’ve undergone orthodontic treatment later in life.
The length of time you’ll need to wear a retainer after braces — and what type, whether a removable appliance or one permanently attached — will depend on a number of factors including the type of malocclusion, your individual mouth structure and age. We’ll recommend the best option that ensures the best chance of keeping your teeth in their new position.

If you’ve ever looked at younger photos of yourself, you’re sure to notice differences with your present appearance. Of course, your basic features might appear much the same. But maybe your lips seemed a little thicker back then, or your nose a bit less prominent.
This is because your facial features don’t stop growing when you reach adulthood—they continue to change throughout your life. For example, lips reach their maximum thickness by around age 14 for girls or age 16 for boys; they’ll remain at that level of thickness for a few years before gradually thinning throughout adulthood. The nose will also continue to grow, becoming more prominent especially as changes in the lower part of the face can make the chin appear shorter.
Although each of us ages at different rates and in different ways, these general physical trends are somewhat predictable. That’s why we can use the knowledge of how our facial physiology changes with age to fine tune orthodontic or other cosmetic dental treatments. The most optimum approach is to consider treatment in the early stages of bite development during childhood or early adolescence.
This means we’re doing more than correcting a patient’s current bite: we’re also taking into account how tooth movement now might affect the jaw and facial structures later in life. By incorporating our understanding of age-related changes into our treatment we might be able to provide some hedge against the effects of aging.
This approach starts with early comprehensive dental care, preferably before a child’s first birthday, and an orthodontic evaluation at around age 6 to assess bite development. It may also be necessary to initiate interceptive treatment at an early age to lessen or even eliminate a growing bite problem to help ease the extent of future treatment. And if a bite requires correction, early evaluation can help create a timetable for effective treatment in later years.
Taking this approach can correct problems now affecting both dental health and appearance. But by acknowledging the aging process in our treatments, we can build the foundation for a beautiful smile well into the future.
There are a few things you need to do — and not do — while wearing braces: avoid hard or sticky foods, for example, or wear protection during sports to avoid injury. There's one important thing, though, that should be at the top of your list — extra attention to daily brushing and flossing.
The fact is your risk for developing tooth decay or periodontal (gum) disease increases during orthodontic treatment. This is because the braces make it more difficult to reach a number of locations around teeth with a toothbrush or floss. Bacterial plaque, the source for these dental diseases, can subsequently build up in these areas.
Teen-aged orthodontic patients are even more susceptible to dental disease than adults. Because their permanent teeth are relatively young they have less resistance to decay than adults with more mature teeth. Hormonal changes during puberty also contribute to greater gum disease vulnerability.
There are some things you can do while wearing braces to avoid these problems. Be sure you're eating a nutritious diet and avoid sugary snacks or acidic foods and beverages (especially sports or energy drinks).Â This will deprive bacteria of one of their favorite food sources, and the minerals in healthy food will contribute to strong enamel.
More importantly, take your time and thoroughly brush and floss all tooth surfaces (above and below the braces wire). To help you do this more efficiently, consider using a specialized toothbrush designed to maneuver around the braces. You might also try a floss threader or a water irrigator to remove plaque between teeth. The latter device uses a pressurized water spray rather than floss to loosen and wash away plaque between teeth.
Even with these efforts, there's still a chance of infection. So, if you notice swollen, red or bleeding gums, or any other problems with your teeth, visit us as soon as possible for an examination. The sooner we detect and treat dental disease while you're wearing braces, the less the impact on your future smile.

We all know Madonna, Seal, David Letterman, Anna Paquin and Michael Strahan (of the talk show Kelly and Michael). What do all of these celebrities have in common? Each has a “signature gap” between their front teeth. Given that they have been in the public eye for quite some time, it's not likely that these famous faces will choose to change their well-known smile. In fact, Michael Strahan has publically stated that he will never close his gap.
However, it is not uncommon for people to desire to fix a small gap in their teeth, particularly in advance of important events, such as weddings. Often times, fixing this small gap requires relatively simple orthodontic movements or tooth straightening. Since the teeth don't have to be moved very far, we can usually use simple appliances to correct the issue within a few months.
In order for us to determine your course of treatment, you'll need to make an appointment with our office for a thorough examination. When we examine you, we'll be looking for a number of items that will affect our treatment recommendation:
- Is there enough room to close the space without creating other bite problems?
- Are the roots of the teeth in reasonably good position to allow for minor tooth movement to close the space? X-rays will be required to make a proper assessment.
- Is there an involuntary tongue habit that has pushed the teeth forward and created the gap? If so, this could be difficult to fix quickly.
- Are the surrounding gum tissues and bone healthy?
Based on our assessment and your individual needs, we may recommend one of the following options:
- Clear retainers, a computer-generated series of clear retainers customized for your bite to move the teeth
- Removable orthodontic retainers to which we will attach small springs or elastics to facilitate the minor tooth movement
- Traditional fixed orthodontic appliances (most commonly known as braces), small metal or clear brackets bonded to your teeth through which tiny wires are used to move the teeth
Regardless of the method we choose, once your teeth have moved into the new position, it is important for you to remember that they must be kept in this position until the bone stabilizes around the teeth. We may therefore advise you to wear a retainer for a few months to a few years, depending on your situation.
